HAS-160 is a cryptographic hash function designed and used widely in Korea. While similar in structure to SHA-1, up to now there was no published attack or security analysis of the algorithm. Applying techniques introduced by Wang et al.[1], we have found collision in the first 45 steps of HAS-160, with complexity 212.
